Product Description
Hollow glass bubbles, also known as glass microspheres or glass bubbles, are tiny, hollow spheres made of glass. They are typically between 10 and 200 micrometers in diameter and are used in a variety of applications due to their unique properties.
One of the main advantages of hollow glass bubbles is their low density. They are much lighter than other fillers such as sand or talc, which makes them an ideal choice for weight reduction in composite materials. They are also highly compressible, which allows them to absorb stress and reduce the overall weight of a material.
Key Applications
- Concrete: Used as a lightweight additive to reduce weight and increase strength in precast concrete, lightweight concrete blocks, and bridge decks
- Plaster and stucco: Used as a lightweight filler to reduce weight and improve workability in interior/exterior walls, ceilings, and decorative features
